ABSTRACT:
An apparatus including a light-emitting device configured to illuminate blood is described. The light-emitting device may include a red light source configured to emit red light. The light-emitting device may also include a green light source configured to emit green light. The light-emitting device may additionally include a first refractive lens and a reflector having a concave surface to reflect a portion of red light emitted by the red light source and a portion of green light emitted by the green light source toward the first refractive lens. The first refractive lens may be configured to direct red light emitted by the red light source to form a red light beam and to direct green light emitted by the green light source to form a green light beam. Additionally, the light-emitting device may include an optical adjuster configured to adjust a separation distance between the first refractive lens and at least one of the green light source and the red light source. The optical adjuster may further be configured to move the first refractive lens with respect to at least one of the red light source and the green light source. A method for illuminating blood is additionally disclosed.
